        <p>
          <span class="application">Falkon</span> is a KDE web browser using
          the QtWebEngine rendering engine. It was previously known as
          <span class="application">QupZilla</span>. It aims to be a
          lightweight web browser available through all major platforms.
        </p>
        <p>
          Although <span class="application">falkon</span> is now part of
          KDE, it can be installed without KDE (with the loss of <span class=
          "application">kwallet</span> functionality).
        </p>
        <p>
          This package is known to build and work properly using an LFS-9.1
          platform.

          Installation of falkon

        <p>
          Install <span class="application">falkon</span> by running the
          following commands:
        </p>
        <p>
          Unless you have installed both PySide2 and ki18n, remove the
          translations for the sample <span class=
          "command"><strong>hellopython.py</strong></span> script:
        </p>
        <pre class="userinput">
<kbd class="command">rm -rf po/</kbd>
</pre>
        <p>
          Fix a missing include in Qt-5.14:
        </p>
        <pre class="userinput">
<kbd class=
"command">sed -i '/#include &lt;QSettings&gt;/a#include &lt;QFile&gt;' \
  src/plugins/VerticalTabs/verticaltabsplugin.cpp</kbd>
</pre>
        <p>
          Now build the program:
        </p>
        <pre class="userinput">
<kbd class="command">mkdir build &amp;&amp;
cd    build &amp;&amp;

cmake -DCMAKE_INSTALL_PREFIX=/usr \
      -DCMAKE_BUILD_TYPE=Release  \
      .. &amp;&amp;

make</kbd>
</pre>
        <p>
          To test the results, issue: <span class="command"><strong>make
          test</strong></span>. All tests should pass. If any fail, the full
          results will be in <code class=
          "filename">Testing/Temporary/LastTest.log</code>.
        </p>
        <p>
          Now, as the <code class="systemitem">root</code> user:
        </p>
        <pre class="root">
<kbd class="command">make install</kbd>
</pre>
        <p>
          If you have installed <span class="application">Pyside2</span> you
          will want to examine the <span class=
          "command"><strong>hellopython.py</strong></span> which is in the
          <code class="filename">scripts/</code> directory, and perhaps copy
          it to your home directory.
